It is a freezing day in January 1962, and Dot Simpson is watching the boats at Limehouse docks, engaged in her favourite daydream: the one where a tall, dark stranger whisks her away to a life filled with warmth and love.
That night, Dot meets Sol, a beautiful pianist from the Bahamas. His easy smile, elegant hands and fascination with her noisy, spontaneous life has her hooked. Their relationship must stay hidden, for Sol's rich parents want him to marry a social equal, and Dot's father believes black man are no better than the devil. But they are young and happy, safe in the knowledge that their love will conquer anything.
Then Dot falls pregnant, and both families are ripped apart. Sol is forced home, his reputation shredded. Dot is thrown out of her house, to give birth in a convent in secret. Separated by oceans, torn apart by loss, can their love survive? Or must they forge new lives, alone?
